AccountsControlHost.exe

Windows ProcessMicrosoft Corporation

Also called accountscontrolhost, accounts control host

WindowsSystem Component

Accounts Control Host. Settings and packaged apps use it when you add or manage a Microsoft or local account in a system dialog.

What you need to know

This hosts the add-account UI. SystemSettings.exe is the Settings app around it.

AccountsControlHost.exe is the Accounts Control packaged host. You see it while adding a Microsoft account or a workplace account. It is not Credential Guard.

Safe?: Yes, as a Windows package
Is it Settings?: Settings can open it
Should I end it?: An add-account wizard will close

Feex says

If I am adding an account and this host is the busy name, that is the wizard. I would not end LsaIso because of it.

What is AccountsControlHost.exe?

AccountsControlHost.exe is the Windows Accounts Control experience. It lives under SystemApps, not System32.

What does it do?

It collects account details and hands them to the account infrastructure. CredentialUIBroker.exe may still show a WAM prompt on top.

Why is it running?

You opened Accounts in Settings, or an app started Add account. The host should exit when the wizard closes.

Is it safe?

Usually safe

The Microsoft AccountsControl package is expected. An AccountsControlHost.exe in Temp is not Settings.

A legitimate copy normally runs from:

C:\Windows\SystemApps\Microsoft.AccountsControl_*\AccountsControlHost.exe

SystemApps package
Opened from Settings Accounts
Not Isolated LSA

Can I end it?

Closes the wizard

Ending AccountsControlHost.exe aborts the add-account sheet. Accounts already on the PC stay. SystemSettings.exe can still open.

Can I remove it?

Do not delete the AccountsControl package. Repair or reset Settings if the add-account page will not open.

Should it start with Windows?

On demand from Settings or an app. Not a tray.

Common problems

Wizard stuck on a spinner

End this host, then retry from Settings. Check the network before you reset Windows.

Confused with CredentialUIBroker

Broker is the token prompt. This host is the accounts page chrome.

Troubleshooting

Diagnose before you change anything destructive.

Settings > Accounts

Reopen add account from there.

Do not download a replacement host

Re-register the SystemApps package only after a broken Settings, as a repair.
